Preparation of heterojunction semiconductor SnS2/SnO2 with enhanced photocatalytic properties

摘要：

　　The formation of heterojunction structure between two semiconductors was considered as an effective method to enhance the photocatalytic activity.Here, we reported a simple method to prepare SnS2/SnO2 heterojunction photocatalysts by annealing SnS2 in air.The structure, morphology, chemical compositions and optical properties of the obtained materials were characterized by the X-ray diffraction (XRD), scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDX) and ultraviolet-visible-near infrared (UV-Vis-NIR) absorption spectra.The photocatalytic investigations showed the composites have higher photocatalytic activity than the single-phase SnS2.The SnS2 powder which annealed at 400 ℃ for 60 min showed the highest photocatalytic performance.
